Sydney, AUSTRALIA — June 3, 2026 — Infosecurity Europe, Stand B48 – DigiCert, a global leader in intelligent trust, today announced findings from a new global survey conducted by independent research firm Omdia, which revealed only 34% of organisations have a complete and current view of their digital certificates. Without centralised visibility into certificates and machine identities, organisations struggle to detect security gaps, prevent outages, and respond to rapidly evolving cryptographic requirements.

DigiCert’s 2026 Global PKI Research Report, titled ‘PKI Under Pressure: The Tipping Point for Modernisation,’ also found that organisations are facing mounting operational and security pressure as certificate volumes and machine identities continue to grow. Nearly three-quarters of organisations are very or extremely concerned about outages caused by expired certificates, while 74% report the same level of concern about certificate sprawl. In response, about 80% are either implementing or planning public key infrastructure (PKI) modernisation initiatives, and more than half expect PKI investment to increase over the next one to three years.

The findings reflect a broader shift in how organisations manage trust amid shrinking certificate lifespans and an explosion of machine identities. As digital infrastructures become more distributed and dynamic, organisations are placing greater emphasis on visibility, automation, and crypto-agility to reduce operational risk and maintain resilience.

“Organisations are reaching a tipping point,” said Lakshmi Hanspal, Chief Trust Officer at DigiCert. “Certificate sprawl, shrinking certificate lifespans, and growing machine identity complexity have pushed manual PKI management past its limits. Most technology leaders know modernisation is necessary to strengthen resilience, but many are still closing the gap on visibility and automation. The shift that needs to happen is clear, centralised platforms that unify policy, automation, and oversight are becoming the foundation for preventing outages and managing trust at scale.”

Additional findings

• Centralised management is a priority, with 76% of organisations saying it is business critical or highly important
• Lack of visibility is the top challenge, followed by siloed solutions (51%) and manual tracking methods such as spreadsheets (47%)
• Modernisation is delivering results, with 64% reporting improved certificate lifecycle automation and 60% reporting fewer outages
• PKI is expanding into new use cases, with roughly 72% to 75% saying it will play a key role in securing artificial intelligence systems
• Quantum readiness remains limited, with only 22% fully assessing systems for future cryptographic risks

The survey was conducted by Omdia on behalf of DigiCert and included more than 400 senior IT and technology respondents across North America, Europe and Asia Pacific. These individuals represent organisations of more than 1,000 employees at a director’s level or higher across a range of industries.
